It's not clear exactly what the extent of Tancredi/Walgreens' direct interest in Dc-Vax is. To me it's quite clear that Tancredi is a guy who is very on top of what is coming in general and hence very significant at least as a significant confirmation that he sees DcVax as moving into the realm of available treatments later this year. For me that is a very good to see signifier that we are indeed on the right track with this investment.
